C protip of the day:
Tired of having pointers that lay around in your functions that /anyone/ can dereference to get your data?!

use the `--->` operator for one-time use struct pointers!

Try it out!
```
#include <stdlib.h>
#include <stdio.h>
struct foo {
int a;
};
int main() {
struct foo *bar = malloc(sizeof(struct foo));
bar--->a = 5; // ok
printf("%d", bar--->a); // Data changed!
return 0;
}
```
